System and a method for ascertaining the mass of at least one animal

1. A system for ascertaining a mass of a plurality of animals each having a radio frequency identification (RFID) tag, the system comprising: a scale configured to support one of the plurality of animals and generate weight information indicative of the mass of each of the plurality of animals weighing by difference each of the plurality of animals when so supported; a RFID reader configured to interrogate the RFID tag when each animal is so supported, and derive animal identification information indicative of an identity of the animal from the RFID tag when so interrogated; and a removable enclosure including an enclosure RFID tag, the removable enclosure configured to receive the plurality of animals one at a time when supported by the scale, wherein the RFID reader is operably coupled to the scale to receive the weight information indicative of the mass of each of the plurality of animals and is configured to interrogate and derive enclosure information indicative of an identity of the removable enclosure from the enclosure RFID tag, and is further configured to generate an electronic animal manifest to be stored in the enclosure RFID tag and includes at least the animal identification information indicative of the identity of each of the plurality of animals, the weight information indicative of the mass of each of the plurality of animals, and the enclosure information indicative of the identity of the removable enclosure.

2. The system defined by claim 1 wherein the scale comprises an electronic scale.

3. The system defined by claim 1 wherein the weight information indicative of the mass of each of the plurality of animals is generated by weighing by difference each of the plurality of animals as the plurality of animals are at least one of incrementally received by the removable enclosure supported by the scale and decrementally removed from the removable enclosure supported by the scale.

4. The system defined by claim 1 wherein the animal manifest is an electronic animal manifest stored in the enclosure RFID tag.

5. A method for ascertaining a mass of a plurality of animals each having a radio frequency identification (RFID) tag, the method comprising: generating weight information indicative of a mass of each of the plurality of animals with a scale; and interrogating the RFID tag of each of the plurality of animals to derive animal identification information indicative of an identity of the animal having that RFID tag, wherein the RFID tag of each of the plurality of animals are interrogated while the animal having that RFID tag is supported by the scale to derive animal identification information indicative of an identity of the animal having that RFID tag, and wherein the weight information indicative of the mass of each of the plurality of animals is generated by weighing by difference each of the plurality of animals as the plurality of animals are at least one of incrementally received by a removable enclosure supported by the scale and decrementally removed from the removable enclosure supported by the scale.

6. The method defined by claim 5 wherein the removable enclosure comprises an enclosure RFID tag that is interrogated to derive enclosure identification information indicative of an identity of the removable enclosure.

7. The method defined by claim 6 further comprising storing in an electronic data store at least one of the animal identification information indicative of the identity of the animal, the weight information indicative of the mass the animal, and the enclosure identification information indicative of the identity of the removable enclosure.

8. The method defined by claim 6 further comprising the step of a processor receiving the weight information indicative of the mass of each of the plurality of animals, the identity information indicative of the identity of each of the plurality of animals and the enclosure identity information indicative of the identity of the removable enclosure and generating an animal manifest for the removable enclosure comprising the animal identification information indicative of the identity of each of the plurality of animals and the weight information indicative of the mass of each of the plurality of animals.

9. A method for ascertaining a mass of a plurality of animals each having a radio frequency identification (RFID) tag, the method comprising: interrogating an enclosure RFID tag of a removable enclosure to derive enclosure identification information indicative of an identity of the removable enclosure; interrogating the RFID tag of each of the plurality of animals to derive animal identification information indicative of an identity of each of the plurality of animals; generating weight information indicative of a mass of the plurality of animals with a scale supporting at least one of the plurality of animals; receiving, by a processor, the weight information indicative of the mass of each of the plurality of animals, the identity information indicative of the identity of each of the plurality of animals and the enclosure identity information indicative of the identity of the removable enclosure; and generating, by the processor, an animal manifest for the removable enclosure comprising the animal identification information indicative of the identity of each of the plurality of animals and the weight information indicative of the mass of each of the plurality of animals, wherein the weight information indicative of the mass of each of the plurality of animals is generated by weighing by difference each of the plurality of animals as the plurality of animals are at least one of incrementally received by the removable enclosure supported by the scale and decrementally removed from the removable enclosure supported by the scale.

10. The method defined by claim 9 further comprising storing in an electronic data store the animal manifest.

11. The method defined by claim 10 wherein the electronic data store is the enclosure RFID tag.
